YouTube Thumbnail Downloader
Paste any YouTube video link to preview and download its thumbnail — from the small default size up to full 1280×720 HD.
About this tool
Every YouTube video automatically gets a set of thumbnail images hosted at a handful of predictable sizes. This tool reads the video ID out of the link you paste — it works with standard watch links, shortened youtu.be links, Shorts links, and embed links — and lays out every available size so you can preview and save the one you need, without opening YouTube or installing anything.
A note on sizes: the full HD thumbnail (1280×720) is only generated by YouTube for some videos, mostly those uploaded in HD. If it's not available for a video, that card will show as unavailable and you can fall back to the next size down (640×480). Click "Download" on any card to save that image, or "Open" to view it full-size in a new tab.
